The 5G topic continues to be highly popular in the industry. The intergenerational evolution of the mobile communications industry is well known from 1G to 5G, but 5G only represents mobile communications. What about fixed networks? In fact, the fixed network has also entered the fifth generation, which we call F5G.


Definition of F5G


The development of fixed networks is driven by business needs and supported by technological development. It has experienced a narrowband era (64Kbps) represented by PSTN / ISDN technology, a broadband era (10Mbps) represented by ADSL technology, and VDSL The ultra-broadband era represented by (30 to 200 Mbps) and the super 100 megabyte era represented by GPON / EPON technology (100 to 300 Mbps) are currently entering the F5G gigabit ultra wide era represented by 10G PON technology. In the future, it may be a 10G era based on 50G PON. The future of fixed networks is all-optical. The technical support of the F5G Gigabit era is all-optical access based on 10G PON. Compared with previous generations of fixed access technologies, F5G Gigabit networks have made rapid progress in three aspects: bandwidth, number of connections, and network experience.


China's F5G network construction leads the world

F5G Gigabit network construction is in full swing. According to the latest statistics from the third-party analyst organization Ovum, 234 operators in 57 countries have released Gigabit broadband services. In China, with industrial policies such as "Broadband China" and competition-driven, the fixed network industry has made great achievements. The FTTH network covering the whole country has been built, and it is at the forefront of the world. As of the third quarter of 2019, the proportion of users with access rates above 100M in China has reached 79.4%, the average fixed broadband access rate has reached 120.2Mbps (estimated value), and the proportion of fiber broadband users in broadband users has reached 91.2% .


F5G and 5G fixed mobile synergy to prosper gigabit industry

Commercial Gigabit broadband services have been deployed in more than 50 countries and have become the mainstream application for the next decade. It is predicted that by 2025, the number of global connections will reach 100 billion, and the penetration rate of Gigabit broadband will reach 30%. Network connectivity will be ubiquitous. Through the deep coordination of fixed mobile, the full use of the ultra-high bandwidth of fiber access and the mobility of 5G networks, combined with the massive connection advantages of both, will promote 2H / 2B / 2C full scene intelligence. The arrival of life has become a key foundation for the innovative application of thousands of industries. At the same time, large-scale innovative businesses will feed back the upgrade of fixed network resources and 5G investment needs, and promote vertical industry applications and network infrastructure investment to form a benign sustainable development closed loop. Facing the future, F5G + 5G will work together to dance and double-G and double-up, which will definitely promote the prosperity of the industrial ecology of all parties and open a new era for the development of global fixed networks.

The arrival of the 5G era will definitely increase the demand for communication products such as optical cables, jumpers, splice boxes, cabinets, and network cabinets. Therefore, it is also an opportunity and challenge for the optical communication industry. CCOFC will certainly seize this opportunity to provide high-quality products and services for 5G construction and contribute our own strength.
